7 Claims. (01. 88-26) My invention relates to frame mountings for slidessuch as are used extensively in motion picture machines as a medium foradvertising or which are used in schools and churches for educationaland other purposes.

An important object of. this invention is to improve generallyupondevices of this character in such a manner as to simplify theconstruction and cheapen the manufacture of the article, facilitate theassemblying of. the component parts, add to the general appearance,permit of its reuse and greatly economize inthe material used andhandled. I

I-Ieretofore it has been the custom in frame mounting of slides to usetwo or more component parts each of which are provided with an openpicture or light projection area assembled in superposed relation withrespect to the glass or other picture carrying medium. Said parts areusually held together with fastening clips, which when dismantled renderthe frame unsightly and unfit for re-use. Y I .Each of the open pictureareas thus formed entails the use and handling of surplus wastemateriaLadds to the cost of dies, and necessitates the use of exteriorfastenings.

My improved invention involves the use of but a single piece ofmaterial;a blank, out, molded or otherwise formed, the sides composing the baseframe being provided with a depending flap which is adapted to be bentover the edge portion of the slide and having a gummed surface foradherence of the same thereto, the depending flaps being mitered in sucha manner that when they are assembled their abutting edges fit withexact nicety and form a secondary frame oppositely disposed to the baseframe having an open picture area complementary to that of the openarea, field, or background formed in the blank which is directlyopposite thereto.

The base frame may be provided with a relief, recess or boundaryindicator of some nature whereby when the slide is placed thereon it maybe temporarily positioned until the return folds are made on allsidesand the process of mounting is completed, or the surface on which aportion of the slide rests may be gummed and such surface preventdisplacement of the slide until the gummed edges of the flaps are foldedover on the adjacent portions of the slide in an opposed relation to thebase frame, thus permitting the use of a single apertured flat piece ofmaterial. I

It is quite obvious the depending flaps, could be 5 formed with asimilar relief or recess, whereby when they are folded TES PATENT OFFICEover and applied they would prevent displacement of the slide in theframe as'will be more in the latter instance could be omitted.

It is to be further understood and the invenfully hereinafter set forth,the relief in the base frame tion isalso to be broadly interpreted thatthe relief in the base frame and the secondary'frame depending from thebase frame could be constructed with a corresponding relief so that thesum of the two reliefs would equal that of the thickness of the slide.

An important feature incorporated in the construction of the mounting isthe perforating of the furrowed line from which the flaps depend fromthe base frame, whereby the accumulated heat from the source ofillumination may find egress, thus insuring a uniform temperature of theslide throughout.

Other features, objects and advantages of the invention will hereinafterappear as the invention is disclosed, but the foregoing will serve tobroadly signify the basic For the. purpose of accompanying drawingintent of the invention.

} better understanding the scope of the invention, reference is made tothe which forms'a part of this specification whereon are shown a plu-lrality of species all of which are covered in the claims.

The figure. analysis follows of said drawing is as Fig. 1 is asemi-perspective front elevation of a lantern slide mounting ventiononly a fragmentand that portion being a struction shown in Fig. 1.

Fig. 3 is a plan view blank shown in Fig. 1 in in accordance with mythereof being shown.

accordance with my inof the slide being shown modification of the conofthe frame mounting unfolded condition.

Fig. 4 is a plan view .of the frame mounting blank shown in Fig. 2 in ani Fig. 5 is an enlarged section taken on line 5--5 of Fig. l, and

Fig. 6 is an enlarged section taken on line Q of Fig. 2.-

unfolded condition.

In Figs. 5 and 6 the extended or unfolded position is indicatedin dottedlines.

It is obvious from the views case the left hand view spond with theright han taught in Figs. 5 and 6,

shown that in either could be made to corred view and vice 'vers'a.

from the construction ondary'frame could be made dependent from thelower right hand base frame and the upper right hand secondary framecould be made dependent from the lower left hand base frame and viceversa 1 to obtain sub-combinations of different interpretations of theinvention.

In the construction taught by the severalviews I construct my inventionof a single blank piece of material, of suitable cardboard or molded orresilient cast material such as celluloid or the like comprising a baseframe consisting of integral top and bottom frame members 1 and 2 andside members 3 and forming an apertured opening or field area 4 throughwhich the picture is exposed. This opening or field area is usuallydetermined by standard existing conditions which must be complied with.

Depending from the top, bottom and side frame members 1, 2 and 3,forming the base frame, are integrally formed flaps 5, 6, and 7, whichare adapted to be bent or folded over the side edges of a slide 8 toform a secondary frame as shown in Fig. 1 having an apertured opening orfield area 4a complementary to the field area 4. All along the extremityof the slide or the boundary thereof as seen in Fig. 2 is a furrowedline designated at the top and bottom by numerals 9 an 10 and at theside by numeral 11. a

This is the bend line of the base frame from which the flaps asbeforeindicated, depend. Said flaps 5, 6 and 7 are mitered from theintersecting point of lines 9 and 11 and ,10 and 11 in such a mannerthat when said flaps are bent in a manner taught by the construction inFig. 5 the edges 12 and 13 and 14 and 15 will abut with exact nicety toform the open picture area 4a to correspond in exact harmony with thatof the open picture area 4:.

The base frame composed of members 1, 2 and 3 may be formed with apartial or whole relief 16 corresponding to the thickness of the slidewhich is adapted to borderize the slide whereby it may be positionallyheld within the frame mounting While the flaps are being securedthereto.

The construction taught by Figs. 1, 3 and 5 may be modified tocorrespond with that shown in Figs. 2, 4 and 6 whereby the relief 16 iseliminated and a boundarial indication as indicated by intersectinglines 1'7 and 18 may be printed on the baseframe to indicatethe locationof the slide and the area bounded within these lines may be gummed toproperly adhere the slide and the mounting. By inserting a thin sharpmember between the two surfaces when once adhered they can be easilyseparated without disfigurement, thereby permitting the re-use of theslide holder.

The flaps 5, 6 and '7 may also be mitered and provided with a recess 19whereby when the flaps 2D, 21 and 22 depending from the base framecomposed of members 23, 24 and 25, similar to members 1, 2 and 3 arefolded over the slide as taught by Figs. 2 and 4, the relief thus formedwill prevent displacement of the slide within its holder. 7

Flaps20, 21 and 22 may be gummed' in the same manner as fiaps 5, 6 and 7whereby the secondary frame thus formed may be easily adhered totheslide or dismantled as aforesaid.

In Figs. 2, 4 and 6 it will be noted the furrowed lines 23, 24 and 25are provided with perforations 26.where they bend, to facilitate egressof the heat contacted by the slide while it is being subjected to theintense heat of illuminating rays.

,That part of the slide holder which projects beyond theslide itself isprovided for, for the following reasons.

It maintains the standard size of the entire slidand 18.

able member which is interchangeable in machines used for lantern slideprojection and lecture work. It permits an economy of glass and reducesweight in handling and shipping; It furthermore cushions the shock of afall when the slide is dropped, so that it seldom, if ever, breaks.

In assemblying the slide and the slide mounting, the slide 8 is placedwithin the relief 16 or positioned within the boundarial indications 1'7The depending flaps are then each in turn folded over upon the face ofthe slide and adhered thereto.

Such a method of mounting lantern slides is simple, inexpensive anddignified. Such a mounting also permits the use of varying colors in thematerial used whereby different classes of slides may be readilydistinguished one from the other. The color variation also enhances theappearance and adds to the attractiveness of the slide.

The following is claimed:

1. The combination with the slide, of a slide holder, comprising a baseframe provided with a boundarial indication adapted for positioning saidslide relative to said holder and a relatively narrow slide retainingflap depending from each side of said frame adapted to be folded overupon the edges of said slide to form a secondary frame cover cooperatingwith said base frame to-retain said slide therebetween.

2. A slide holder consisting of a single piece of octagonal materialincluding a'base mat having a projection opening, a relatively narrowflap depending from the respective sides of said base mat foldable overthereupon, said flaps when in folded over relation forming a secondarymat, the adjacent inner edges of which enclose a projection openingcorresponding in area to first said opening in combination with a slideresting between said mats and being securable thereto.

3. A frame mounting for a lantern slide comprising an apertured base matprovided with a mete adapted for positioning the slide withrespect toits mat, there being a marginal portion extending beyond said mete, thelimits of which are defined by a scored line, relatively. narrow mantleflaps provided with an offset ledge depending from said scored linefoldable over upon said slide, said ledges abutting the edges of saidslide, and the remaining portions of said fiaps extend over said slidesto form a secondary cover mat for said slide, the adjacent inner edgesof which enclose an aperture the area of which corresponds in size andposition to the aperture in said base mat, and means to adhere said basemat and flaps to said slide whereby to maintain the slides designatedposition.

4. A picture slide holder consisting of a single piece of octagonmaterial having, a projection opening a relatively narrow flap dependingfrom each of the parallel sides forming said projection opening foldableoverand adapted to overlap and hold a picture slide therebetween, saidfiaps thus forming a secondary frame securable to said slide andenclosing a secondary projection opening corresponding in area andposition to first said opening, positioning means carried bysaid baseframe for indicating the placement of the slide thereupon in relativerelation to said projection opening, there being a marginal portionsurrounding said slide terminating at a bend line from which each ofsaid flaps are subtended, said bend line being scored with perforationsto facilitatefolding said flaps and to also provide egress for the heataccumulated by said slide from the rays of illumination to which it issubjected.

5. A lantern slide frame comprising a base mat having a projectionopening and a relatively narrow flap depending from the respective sidesof said frame adapted to be folded over upon a slide resting on saidmat, said flaps being provided with a relief to provide a slide seat andadhered to said slide in a manner so that the opening thus formed by theadjacent inner edges of said flaps is complementary to first saidprojection opening.

6. A picture slide holder, comprising a base member having a rectangularprojection opening in combination with a transparent slide restingthereon and covering said opening and the marginal portion of saidholder adjacent said opening, said holder being provided on all sideswith relatively narrow foldable flaps, the folding lines of which arelocated in outwardly spaced relation to the edge portions of said slidein order to provide a slide protecting marginal portion in the holder,said flaps being provided with an offset ledge and adapted to be foldedover upon and secured to a facial portion of said slide with said ledgesabutting the edges of said slide, said flaps in their folded positionhaving a width corresponding to that of said base member, the adjacentinner edges of said flaps enclosing an opening in size corresponding tofirst said opening, the edges of the two-projection openings thus formedbeing substantially flush.

7. The combination with the slide, of a slide retaining frame comprisinga one piece mat of octagon shape including an apertured base frame andrelatively narrow flaps depending from the edges of said base framefoldable over upon and securable to the slide, the oblique sides of theoctagon forming a miter whereby the ends of the overlapping portion ofsaid flaps abut, and the adjacent inner edges of said flaps enclose anopening corresponding in size to the aperture in the base frame with theinner edges of both openings substantially flush.
